(or, rather, how I am).Īh, figured it out.This function takes two parameters, namely array name followed by a mode that denotes the dimensions. So, among other things, $max is obviously not meant to be an Array, but I’m not quite sure how it seems to be getting in such a muddle. So, running this to get the var_dump gives this: PHP Notice: Array to string conversion in /var/www/site1/test.php on line 35
$prev=readdb($p_arg,$con) # this tries to get the previous record before the current one $next=readdb($n_arg,$con) # this tries to get the next record after the current one The readdb function now looks like this, and at least produces a result: function readdb($arg,$con) I now have it near enough working, but still one error message I don’t quite understand, and I haven’t yet figured out how to change it over to using prepared statements.įor ease, I have continued to use the global conn, (but changed it to “con”), and now pass it across to each function I use. While the code I’m testing looks like this: =1))Īny help and pointers in the right direction would be very much appreciated.
PHP Notice: Undefined variable: conn in /var/www/site1/test.php on line 12 Notice: Array to string conversion in /var/www/site1/test.php on line 11 PHP Notice: Array to string conversion in /var/www/site1/test.php on line 11 Warning: mysqli_fetch_array() expects parameter 1 to be mysqli_result, null given in /var/www/site1/test.php on line 13 PHP Warning: mysqli_fetch_array() expects parameter 1 to be mysqli_result, null given in /var/www/site1/test.php on line 13 Warning: mysqli_fetch_assoc() expects exactly 1 parameter, 2 given in /var/www/site1/test.php on line 12 PHP Warning: mysqli_fetch_assoc() expects exactly 1 parameter, 2 given in /var/www/site1/test.php on line 12 So, the error messages are as follows: Notice: Undefined variable: conn in /var/www/site1/test.php on line 12 I have added debugging code so that I can see where the errors are, but I really don’t quite understand either (a) why they are errors to begin with, or (b) the error message, or (c) how to fix them. However, despite lengthy searches of similar issues I don’t seem to be able to make any progress. I’m really not too familiar with PHP, but have attempted to update the bits which I’ve learned are no longer supported (notably mysql functions). The script is basically trying to do a few simple things by connecting to a database and reading off a record, and then getting the results from an array. The current machine I’m using runs CentOS-7 and is using PHP 7.3.9.
So, I’m attempting to update some PHP, which used to work a long while ago on older versions of PHP, but I’m running into many issues. I did already ask this question on Stack Exchange or somewhere, but didn’t get anywhere, so I’m hoping someone on here can assist, or at least help me understand some of it a bit more.
